Simpson BP 5/8-3 Bearing Plate is engineered to give a greater bearing surface than standard cut washers, helping to strengthen and distribute the load at critical structural connections. Built from heavy 3-gauge uncoated steel and sized at 3 in. x 3 in. with a 5/8 in. bolt hole, this bearing plate is a dependable upgrade over cut washers wherever foundation anchor bolts must transfer concentrated compressive forces reliably into the surrounding structure.

Key Features

• 5/8 in. bolt diameter compatibility - fits standard 5/8 in. anchor bolts, making it a direct, no-modification replacement for cut washers at foundation connections.
• 3 in. x 3 in. plate size - the larger footprint spreads load across a wider surface area, reducing the risk of localized stress and bearing failure at anchor points.
• 3-gauge steel construction - the heavy plate thickness delivers the rigidity needed to handle demanding compressive loads without deforming under pressure.
• Uncoated steel finish - the bare steel surface is ready for field application or additional treatment as required by the project, with no coating to interfere with custom finishing.

Why This Product

• More effective load distribution than cut washers - the 3 in. x 3 in. bearing area is significantly larger than a standard cut washer, putting more material between the bolt and the substrate to spread force and protect the connection.
• Purpose-built for foundation anchor bolt applications - designed specifically to replace cut washers on foundation anchor bolts, this plate addresses one of the most load-critical connection points in structural assemblies.
• Heavy-gauge steel for high-load reliability - 3-gauge construction means the plate resists bending and compression at the connection, giving builders confidence in structural integrity where it matters most.
• Trusted Simpson engineering - backed by Simpson's reputation for structural connector design, this bearing plate is built to consistent dimensional standards that professionals can count on for critical connections.

Frequently Asked Questions

What is the purpose of a bearing plate compared to a standard cut washer?

Bearing plates give greater bearing surface than standard cut washers. They are designed to help strengthen and distribute the load at critical connections, making them a more effective solution for high-load applications such as foundation anchor bolts.

What bolt diameter is this bearing plate designed to accommodate?

The BP 5/8-3 is designed for use with a 5/8 in. bolt diameter.

What are the dimensions of the BP 5/8-3 bearing plate?

The bearing plate measures 3 in. x 3 in. and is made from 3-gauge steel.

Where is the BP 5/8-3 bearing plate typically used?

Bearing plates are typically used on foundation anchor bolts in place of cut washers, providing improved load distribution at these critical structural connections.
